> As part of HIVE-11304, we moved from Log4j1.x to Log4j2. But DataNucleus log
> messages gets logged to console when launching the hive cli. The reason is
> DataNucleus is trying to load Log4j1.x Logger by traversing its class loader.
> Although we use log4j-1.2-api bridge we are loading log4j-1.2.16 jar that was
> pulled by ZooKeeper. We should make sure that there is no log4j-1.2.16 in
> datanucleus classloader hierarchy (classpath).
> DataNucleus logger has this
> {code}
> NucleusLogger.class.getClassLoader().loadClass("org.apache.log4j.Logger");
> loggerClass = org.datanucleus.util.Log4JLogger.class;
> {code}
